javax.persistence.Lob - JPA annotation

Annotation Lob

Fields (including property get methods)
Specifies that a persistent property or field should be persisted as a large object to a database-supported large object type.

Portable applications should use the Lob annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with the Basic annotation or the ElementCollection annotation when the element collection value is of basic type. A Lob may be either a binary or character type.

The Lob type is inferred from the type of the persistent field or property, and except for string and character-based types defaults to Blob.

Example 1:

   @Lob @Basic(fetch=LAZY)
   protected String report;

Example 2:

   @Lob @Basic(fetch=LAZY)
   @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
   protected byte[] pic;
